AeroShell Turbine Oil 750是一种7?mm2/s的合成混合酯油，含有增稠剂和添加剂，可提供良好的负载、热稳定性和氧化稳定性。
AeroShell 750涡轮机油的开发旨在满足DERD 2487（现为DEF STAN 91-98）的要求，并为英国民用燃气轮机提供高标准的润滑，特别是涡轮螺旋桨发动机，其中螺旋桨减速齿轮箱需要良好的承载油。
AeroShell涡轮机油750也被俄罗斯批准为MN-7.5u的类似物，适用于需要使用矿物涡轮机油和飞机活塞发动机油混合物的俄罗斯涡轮螺旋桨应用。
AeroShell Turbine Oil 750含有合成酯油，不应与不相容的密封材料接触使用，也会影响某些油漆和塑料。
